What do you varnish brushers do with your bruses between coats? I am used to working with shellac, so have been somewhat blasé about care for my brush between coats--a quick squirt of alcohol takes care of it if it dries out too much. But that approach doesn't work so well with varnish
I'm trying waterlox sealer/finish, and have been leaving finish on the brush and wrappng it tightly in aluminum foil. But enough air is getting in for some evaporation, and I worry that it might start curing in the brush.
Do you fully clean your brushes between coats? Leave soaking (bristles only) in paint thinner/MS/naptha? Half-way clean with thinner, then wrap wet until next coat? What is "best practice"?
